changing skin layout

I am using the Charlie theme(skin) and was wondering is there is
a way to centre align my logo in the middle of the page instead of
left aligned. And also how to centre align the pages underneath the
logo....so that everything is centre aligned .

Is the site going to be upgraded at some stage? We don't support CSS,
but in the case of an upgraded site we can assist on writing the
necessary code if the site is due for an upgrade, and of course if the
skin isn't going to be switched out as that will make the work
involved redundant.
